Brake bleed after changing proportioning valve

I removed the 18 bar proportioning valve and installed the 55 bar valve last night and now I've got to bleed the brakes. Do I need to bleed the whole system or can I just bleed the master cylinder?

Try the master and if it feels spongy then do the whole system. The air bubble(s) in the valve will not necessarily cooperate.
